Don't assume that this PR campaign is representative about how 'the left' views firearms. I'm sure if you look at any right-wing cause du jour you would find similar, if not more outrageous, PR campaigns to promote that issue. For the most part, those on the left and center of the political spectrum are strong supporters of the second amendment. I am one example. I own them, use them, and respect them. I believe that our current laws are overall okay, but there are some issues that need to be fixed.
The difference is that although we do value and respect firearms' role in our society, we don't bring it to the level of idolatry that the right does. It is okay to tweak and update our firearms regulations as we learn from our experience. Doing so does not solicit an immediate "OMGOBUMMERISCOMMINGFORYERGUNS!!!" reaction from us. An example of this type of reaction was the sharp rise in firearm and ammunition purchases right around the time of the elections, despite the fact that Obama hasn't effectively done or even proposed anything to tighten restrictions to an unacceptable level. I may not agree with what little he has proposed, but the right's reaction is wholly unjustified. Some common sense needs to be applied and we are at least willing to have the conversation instead of plugging our ears.
So yeah, you caught us. Our secret is out. We're coming to take your guns with jackboots and everything. Oogabooga!
